Method and apparatus for transmitting/receiving control channel in wireless communication system

A base station apparatus for comprising a resource region, the apparatus comprising:

• a transceiver configured to transmit and receive a signal to and from a terminal, respectively;
• and
• a controller configured to control comprising a Resource Block (RB) for transmitting a control channel,
• wherein an interval between subcarriers corresponding to Resource Elements (REs) constituting a same Control Channel Element (CCE) included in the RB is 4 in each symbol of the RB with the exception of a symbol in which a Demodulation Reference Signal (DMRS) is allocated.

A terminal apparatus for receiving a control signal, the apparatus comprising:

• a transceiver configured to transmit and receive a signal to and from a base station, respectively;
• and
• a controller configured to receive a control channel from a base station based on a Resource Block (RB),
• wherein an interval between subcarriers corresponding to Resource Elements (REs) constituting a same Control Channel Element (CCE) included in the RB is 4 in each symbol of the RB with the exception of a symbol in which a Demodulation Reference Signal (DMRS) is allocated.
